D155 Board of Education Approves Two New Vice Principals
The Board of Education approved Lori Ratliff as vice principal at Crystal Lake South High School and Kevin Koeppen as vice principal at Prairie Ridge High School on Thursday, January 24. They will begin their roles on July 1.

“Beyond the experience both Lori and Kevin bring to these positions, they believe in and demonstrate District 155’s mission to inspire, empower, and nurture our students,” said Steve Olson, superintendent. “Their strengths align with our strategic planning goals specifically in the areas of student well-being and collaborative partnerships, which will benefit our students and move District 155 forward.”

Lori Ratliff is a proud alum of Crystal Lake South High School, and she will transition from her role as assistant principal for educational services into the vice principal position. She also has served as a humanities division leader and English teacher at South since 2002. Ratliff has worked to implement new social-emotional supports for students, create a new model of professional learning for teachers and help students connect career paths to course selection.

“I am so proud of the progress we are making to ensure that social-emotional learning is at the heart of our curriculum. I’m humbled and excited to serve my school and my district in this way,” said Lori Ratliff, Crystal Lake South vice principal.

Kevin Koeppen joined District 155 in 1999 and has served as a division leader of industry and careers and wellness for the last five years and department chair prior to that. He also served as an assistant athletic director and coach. Koeppen has initiated various partnerships with educational stakeholders and community members in an effort to connect curriculum to real life applications and expose students to career opportunities.

“Preparing young adults socially, emotionally, and academically for future endeavors beyond their high school years has always been a passion of mine. I believe it is imperative to give students opportunities to learn college and career-specific skills through all content areas in order to prepare them for their future endeavors,” said Kevin Koeppen, Prairie Ridge vice principal.

Joe Cole, vice principal at Crystal Lake South High School, and Lisa Connell, vice principal at Prairie Ridge High School, will retire later this year. Connell began her career in District 155 in 1986 and Cole joined the district in 1987.

D155 Reaches Agreement with D155 Education Association
The District 155 Board of Education approved the teachers’ contract on Thursday, January 24. The D155 Education Association, district administrators, and the Board of Education have been working collaboratively toward a new collective bargaining agreement since August. The contract is for three years and will run July 1, 2019 to June 30, 2022.

“This has been a collaborative process between the board and representatives with our education association. We believe we have reached an agreement that allows us to retain and recruit high quality teachers while being mindful of our taxpayers,” said Adam Guss, Board of Education president.

A summary includes changes that will be instituted in the new collective bargaining agreement:

  • The new agreement provides an average increase in base salaries of 1.5% in each of the three successive years of the contract with corresponding total annual increases of 3.87%, 3.86%, and 3.87% in each of those same three years of the contract for teachers who have achieved a step increase due to experience in the District. When compounded, this contract represents a 12.0% total increase over three years to the salary and benefits (TRS, Health Insurance, Etc.) for teachers.

  • Elimination of mandatory union dues (so-called “Fair Share”) in keeping with the recent decision of the United States Supreme Court.

  • Increase in the stipend for traveling teachers who teach 30 periods per week and have more than 3 course preparations from $500 per semester to $1,500 per semester.

  • Post master’s degree college credit reimbursement to a maximum of 15 graduate credits annually in high needs areas as directed and approved by the district.

  • Teachers are only eligible to receive course reimbursement of $350 per credit hour for approved masters programs following the completion of two full years of teaching.

  • Salary caps (3% annually) for teachers within four years of eligibility for retirement.

  • A retirement “pipeline” providing 3% annual increases for four consecutive years for teachers who submit their irrevocable intent to retire letter.

  • Creation of a joint salary schedule committee charged with the mission to study alternative methods for teacher compensation.

“Our team and the district representatives came to the table with a shared commitment to do what’s best for our students, our schools and the long-term health of the district. We worked from that common ground to craft a fair deal that will allow us to continue offering our students the excellent experience they deserve,” said Devin Hester, D155 Education Association president.

The D155 Education Association ratified the agreement on Friday, January 18.

“The feedback we received during our strategic planning process this fall from more than 4,600 students and parents highlighted the quality education we offer in District 155 and emphasized  our caring, dedicated faculty and staff. This agreement honors what we value as a community while continuing to be fiscally responsible,” said Steve Olson, superintendent.

Tax Levy Proposal Saves Taxpayers at Least $1.7 Million Per Year
District 155’s Board of Education approved a tentative tax levy proposal that will save taxpayers at least $1.7 million per year on November 20.

District 155 proposed an estimated increased tax levy, however the district will pursue a state Property Tax Relief Grant which provides school districts an opportunity to lower the burden on local taxpayers. The district will permanently reduce its operating levy to flat or lower after the state notifies the district if it is awarded the grant in late January.

“We want our taxpayers to know we’re listening to them, and we understand their concerns about their tax bills. This year’s tax levy process, despite an estimated increase, will result in a savings to our taxpayers every year moving forward,” said Jeremy Davis, assistant superintendent of finance and operations.

The estimated savings for a $200,000 house is $53.14 for the District 155 portion of the tax bill. The tax rate for District 155 has dropped three consecutive years, and the tax rate is 12.7 percent less than it was in 2014.

“As one of the top performing districts in McHenry County, District 155 will have levied flat two of the past four years. We understand the impact great schools can have on local property values, and we’re proud to be part of a community that values education,” said Adam Guss, Board of Education president.

Rhew, LCPC and Dr. Robin Choquette have combined over 35 years working with professionals and parents clinically and have provided over 400 trainings both locally and nationally on a wide array of topics relating to parenting strategies and raising resilient children through goal directed parenting.

5Essentials Survey

Each school year, students, teachers and parents across Illinois have an opportunity to participate in the annual statewide Illinois 5Essentials Survey. This survey is designed to generate a detailed picture of the inner workings of your child's school. As a parent, this opportunity will allow you to share your thoughts on the important elements of school effectiveness in a survey about your child's school.

On behalf of the Illinois State Board of Education, the Illinois 5Essentials Survey will be administered online by UChicago Impact at the University of Chicago. The survey gathers data related to five indicators that can predict important student outcomes, including improved attendance and larger test score gains. These five indicators that affect and predict school success are:

· Effective Leaders

· Collaborative Teachers

· Involved Families

· Supportive Environments

· Ambitious Instruction

Prior research in more than 400 schools has shown that schools that were strong on at least three of these "5Essential" indicators were 10 times more likely to improve student learning gains in math and reading than those that were weak on three or more Essentials.

All teachers and 6th through 12th grade students along with all parents will be responding to this survey. 5Essentials Reports will be generated for schools. These reports will be included in the State School Report Card.

Your participation in the parent portion of the survey will help us understand the conditions at your child's school and guide improvement. Your identity and survey responses will be kept completely confidential and will never be connected to you or your child.

The Illinois 5Essentials Survey will be conducted January 16 through February 15, 2019. To take the survey please visit and select the appropriate survey to begin.

De parte de la Junta Estatal de Educación de Illinois, el Estudio de 5Essentials se administrará en línea por UChicago Impact de la Universidad de Chicago.

· Collaborative Teachers (Maestros Colaborativos)

· Involved Families (Familias Dedicados)

· Supportive Environments (Ambiente Soportante)

Investigaciones anteriores en más de 400 escuelas han demostrado que las escuelas que eran sólidas con al menos tres de estos indicadores "5Esenciales" tenían 10 veces más probabilidades de mejorar las ganancias de aprendizaje de los estudiantes en matemáticas y lectura que aquellas que eran débiles en tres o más indicadores "Esenciales."

Todos los maestros y todos los estudiantes en sexto a duodécimo grado, junto con todos los padres, responderán a esta encuesta. Informes de los 5Essentials serán generados para las escuelas. Estos informes se incluirán en el 'Boletín de Notas del Estado.'

Su participación en la encuesta para los padres nos ayudara a comprender las condiciones en la escuela de su hijo, y esa información se puede usar para mejorar la escuela. Su identidad y sus respuestas se guardarán en forma totalmente confidencial y nunca será conectado a usted o a su hijo.
